can not be applied to the stem. The invention further contemwhich are designed to engage the casingto limit the upward movement of the cover and prevent the same from being moved beyond a vertical position. In. the present instance the cover can only belifted through an angle of approximately forty-five degrees and with this construction it will be obvious that as soon as the cover has been released the action of gravity will again move the same into a closed position. A pair of coil springs 17 are also rovided at the pivot end of the cover and serve ,to normally swing the cover into a closed position.

Having thus described the invention, what is claimed as new is: p a

1. The combination of a valve embodying a rotary plug, a stem projecting from the plug, a removable wrench adapted to have an interlocking connection with the stem for turning the plug, and a cover u on the valve adapted to engage the stem to ock the plug agalnst movement.

2. The combination of a valve embodying a rotary lug, a stem projecting from the plug and ormed with a notch, a removable wrench adapted to be applied to the stem and to engage the notch for turning the plug,

and a cover applied to the valve and formed with a wing a apted to engage the notch'to lock the plug a ainst movement.

3-. The comblnation of' a valve embodying a rotary plug, a stem projecting from the rotary" plug, an indicator plate applied to the stem so as to'rotate therewith and indicate the position of the valve, a removable wrench adapted to detachably engage the stem for in, the casing being provided with a groove communicating at its ends with upwardly extending channels, a"*stem projecting from the plug and formed with a notch, a removable wrench adapted to engage the stem and the notch therein to turn the plug, the said wrench being formed with a returned lip which travels within the groove in. the casing and is opposite one of the channels at the ends of t e groove when the valve is in either an. open or a closed position, and a cover mounted upon the valve casing, the said cover. being rovided with awing for engaging the notc h in the stem to lock the plug .against movement.

5 The combination of a valve embodying a casing having a rotary plug mounted therein, the casing being formed with a groove communicating at its ends with upwardly extending channels, a stemprojecting from the plug and formed withna notch, an indicator plate applied to the stem and provided with means for engaging the notch whereby the indicator plate is caused to.rotate with the stem to indicate the osition of the valve, a removable wrench a apted to be applied to the stem and to engage the notch therein for turning the plug, the wrenchbeing formed with a returned lip which travels within the groove and is opposite one of the channels In testimony whereof I affix my signature i of two witnesses. p
